DNV-GL , the maritime, oil and gas, and energy industries’ premier classification and technical assurance organization with a purpose to advance safety of life at sea, posted the January 2018 revision of the DNV-GL Battery Power rules, which supersedes the July 2017 edition of DNVGL-RU-SHIP Pt.6 Ch.2. The modified rules cover propulsion, power generation, and […]
As renewable energy becomes more common, it is apparent that lithium battery powered energy storage systems present a significant fire threat. In response, the 2018 International Building Code requires an energy storage system to be able to contain a runaway lithium battery cascading event. Several energy storage companies are UL tested and certified in accordance […]
The Penn State draft report: Safety of Lithium Nickel Cobalt Aluminum Oxide Battery Packs In transit Bus Applications (February 2016), concluded: “This test resulted in confirming this material as a viable candidate for use with NCA cells, see figure 52. It is able to maintain structural integrity and not melt or burn during or following […]
As the use of lithium batteries continues to proliferate, the need to contain a possible runaway fire event becomes a serious consideration for people who use electric vehicles, energy storage systems, aircraft systems, or micro electronics, which is just about everybody. What is beyond the “ordinary use of lithium batteries” is the application of high […]
As described by Transport Canada, Lithium batteries fall into the same category as gasoline, propane and sulphuric acid and, as such, are considered to be 'dangerous goods'. Here are the hazards associated with transporting lithium batteries :
When developing or upgrading to a fire resistant Pack Design Specification, consider the following 10 requirements: 1. Prevent Thermal Runaway Battery Propagation Provide significant separation between cells to segregate runaway events and provide a radiant barrier between cells. 2. Vent Flammable electrolyte outside of the pack. Venting electrolyte and stopping the propagation of heated electrolyte […]
